Using the VA Tester is very similar to the USB Tester. The right side of the VA Tester is the input and the left side is the output. Using the screw terminals you can attach wires or even jumper wires that are terminated. From the front the top contacts are positive and the bottom are negative. There isn’t protection on the tester so make sure you don’t reverse the wires.

To measure voltage place the jumper on the header above the middle white line. Then you can probe the test points on the lower half or connect clips to the headers in the middle below the white line. The right one is VCC and the left one is GND.

First remove the jumper from the header above the white line. Connect your DMM positive probe to the right test point or clip to the right pin of the header. Then do the same for the negative probe to the left test point or left pin of header.
